I am currently running "Windows 10 Home Insider Preview"; Build 10074. Today I received an error stating that my Version of Windows is outdated, and needs to be updated. It also stated that my pc will restart every couple hours, until it fails to start. I have tried using the updater in the "Settings" app, and i get the error code (0x80248014) . I have also tried updating to the Official Win10 release using "Media Creation Tool", but i need a product key? I have also tried changing a few local keys in the Registry Editor but still no luck. I have been an insider for many months, and now if i cannot find a way to update/upgrade from my build 10074, i will not be able to use my pc. Any help on updating would be greatly appreciated.
